What is Numberjack?

Numberjack is a modelling package written in Python for constraint programming. Python benefits from a large and active programming community, Numberjack is therefore a perfect tool to embed CP technology into larger applications. It is designed to support a number of underlying C/C++ solvers as egg files, that is, seamlessly and efficiently. Currently, there are four available back-ends: a MIP solver (SCIP), two SAT solvers (MiniSat) and (Walksat) and CP solver (Mistral).

• Numberjack offers a high level constraint programming language
• Numberjack directly benefits from python's features and modules
• Numberjack uses efficient underlying C/C++ solvers, without the compilation hassle!
